EN 10217-2 Grade P265GH normalized or normalized formed (+N)
EN 10217-2 Grade P265GH normalized or normalized formed (+N) introduction
Electrical welded tubes made of the heat-resistant non-alloy quality steel P265GH are used for steam pressure vessels, tube construction, pressure vessel and apparatus manufacturing mainly in the chemical industry for temperatures up to 200 °C and simultaneous high pressures.
The total load and the special scale relationships may decrease or increase the temperature limit.
